Because anything “+ TITS!” make everything better. Us Magazine reports:

During a live-action sequence on Sunday’s episode of The Simpsons, Perry, 25, vamped it up in a low-cut, skin-tight dress festooned with Homer, Bart, Lisa, Marge and Maggie. During Perry’s visit with puppet versions of the animated family (plus Mr. Burns and barkeep Moe), the recently wed star and the gang crooned “39 Days of Christmas.”

I really don’t understand why science still has to create new technology to convince us that Katy Perry is a singer. She has big tits. Why does she have to suffer the indignity of actually working? What is this outrage? Quite frankly, this makes me embarrassed to be an American.
